Module web

Web

The officially supported browsers are Chrome, Firefox and Safari 13.1+, though forks of these should work fine.

Winit supports compiling to the wasm32-unknown-unknown target with web-sys.

On the web platform, a Winit window is backed by a <canvas> element. You can either provide Winit with a <canvas> element, or let Winit create a <canvas> element which you can then retrieve and insert it into the DOM yourself.

Currently, there is no example code using Winit on Web, see #3473. For information on using Rust on WebAssembly, check out the Rust and WebAssembly book.

CSS properties

It is recommended not to apply certain CSS properties to the canvas:

• transform
• border
• padding

The following APIs can’t take them into account and will therefore provide inaccurate results:

• WindowEvent::Resized and Window::(set_)inner_size()
• WindowEvent::Occluded
• WindowEvent::CursorMoved, WindowEvent::CursorEntered, WindowEvent::CursorLeft, and WindowEvent::Touch.
• Window::set_outer_position()

Structs

• CustomCursorFuture

Enums

• BadAnimation
  An error produced when using CustomCursor::from_animation with invalid arguments.
• CustomCursorError
• PollStrategy
  Strategy used for ControlFlow::Poll.
